I need to acces the attribute class through a loop of names. I wonder how can i make it easy.

def dofun():
   class Dict:
       pass

   fun = Dict()
   setattr(fun, X1, 10)
   setattr(fun, X2, 20)
   setattr(fun, X3, 30)
   return fun

def main():
   fun = dofun()
   for i in range(1, 3):
      print(fun.X + i)
      print(globals()['fun.X' + str(i)])

None of the prints works.. Thanks!

Can you format the code properly? – AMC Dec 19 '19 at 15:08

`getattr(fun, f'X{i}')`…!? – deceze Dec 19 '19 at 15:13

@AMC Code is properly formatted. – tobias_k Dec 19 '19 at 15:13

Can you expand on what your program is meant to do? This is bizarre. – AMC Dec 19 '19 at 15:14

Note that unless you have defined a variable `X1` somewhere, that `setattr` will fail… – deceze Dec 19 '19 at 15:15

Looks like an XY problem. Why not use a regular ``dict`` instead of using an subclass of ``object`` and working with dynamic attributes?
